Facebook bug allowed websites to grab unsuspecting users’ personal data - Security firm Imperva found a bug in May that allowed websites to read Facebook users and their friends’ private information. The troubling vulnerability let a site access users’ likes and interests through a manipulated Facebook Graph query. Thankfully, the bug has now been fixed Imperva’s researcher Ron Masas discovered in May that Facebook was exposed to cross-site request forgery (CSRF). That means another website...

#Starlore Lynx – the lynx. There is a quasar here (APM 08279+5255) whose appearance is being severely warped by gravitational lensing, the influence of an intervening foreground galaxy.

"Using the Next Generation Transit Survey (NGTS), astronomers have identified an energetic flare displaying quasi-periodic pulsations on the pre-main sequence M star NGTS J121939.5-355557. The newly detected flare is one of the most energetic flares seen on an M-type star to date. The finding is reported in a paper published November 5 on arXiv.org."

"Jairo Méndez Abreu and Adriana de Lorenzo-Cáceres, researchers at the Instituto de Astrofísica de Canarias (IAC), have discovered a peanut-shaped structure in the inner bar of a double-barred galaxy close to the Milky Way. Structures of this type, previously detected only in outer bars, are useful tracers of the evolution of the galaxies.

The complexity of the shapes and structures found within spiral galaxies has fascinated astronomers for decades, and is a key to understanding their evolution. One example of this complexity is the galaxy NGC 1291. The French astronomer Gerard de Vaucouleurs discovered a system in this galaxy in which there are two stellar bars, and identified a pattern that he termed "lens-bar-nucleus," which is repeated in the outer and the inner part of the galaxy. This structure is basic for understanding the internal evolution of the galaxies, and how they fuel the supermassive black holes at their centres."

"A letter authored by SETI Institute scientist Oliver White was published by Nature Astronomy today. Co-authors included researchers Jeff Moore, Tanguy Bertrand and Kimberly Ennico at NASA's Ames Research Center in Silicon Valley.

The letter "Washboard and Fluted Terrains on Pluto as Evidence for Ancient Glaciation" focuses on these distinctive landscapes that border the vast nitrogen ice plains of Sputnik Planitia along its northwest margin (Figure 1), and which are amongst the most enigmatic landforms yet seen on Pluto. These terrains consist of parallel to sub-parallel ridges that display a remarkably consistent ENE-WSW orientation, a configuration that does not readily point to a simple analogous terrestrial or planetary process or landform.

"The Gaia satellite has spotted an enormous 'ghost' galaxy lurking on the outskirts of the Milky Way.

An international team of astronomers, including from the University of Cambridge, discovered the massive object when trawling through data from the European Space Agency's Gaia satellite. The object, named Antlia 2 (or Ant 2), has avoided detection until now thanks to its extremely low density as well as a perfectly-chosen hiding place, behind the shroud of the Milky Way's disc. The researchers have published their results online today.

Ant 2 is known as a dwarf galaxy. As structures emerged in the early Universe, dwarfs were the first galaxies to form, and so most of their stars are old, low-mass and metal-poor. But compared to the other known dwarf satellites of our Galaxy, Ant 2 is immense: it is as big as the Large Magellanic Cloud (LMC), and a third the size of the Milky Way itself.

What makes Ant 2 even more unusual is how little light it gives out. Compared to the LMC, another satellite of the Milky Way, Ant 2 is 10,000 times fainter. In other words, it is either far too large for its luminosity or far too dim for its size."

A new technique that makes dead mice transparent and hard like plastic is giving researchers an unprecedented view of how different types of cell interact in the body. The approach lets scientists pinpoint specific tissues within an animal while scanning its entire body.
The technique, called vDISCO, has already revealed surprising structural connections between organs, including hints about the extent to which brain injuries affect the immune system and nerves in other parts of the body. That could lead to better treatments for traumatic brain injury or stroke.
